(PHP Extension) HTML Table to CSVDemonstrates a method for converting an HTML table to a CSV file. Note: This example requires Chilkat v9.5.0.77 or greater.
<?php // The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number. // For example, if using Chilkat v9.5.0.48, then include as shown here: include("chilkat_9_5_0.php"); // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // First download the HTML containing the table $http = new CkHttp(); $bdHtml = new CkBinData(); $success = $http->QuickGetBd('https://example-code.com/data/etf_table.html',$bdHtml); if ($success != true) { print $http->lastErrorText() .
